What is there a battery life on the unit and does it have a low battery indicator?

I think its lasted ten hours. Then it'll start blinking rapidly light blue for a minuet and shut off. I usually have it on during work continuously.

I use mine for workouts between 30 minutes to 2 hours in duration and usually get 2-3 workouts in before I recharge it. Have never had an issue with the battery. The ten hours mentioned by Razor789 is I'm sure accurate. For most activity, I think this will fit your needs. I can't explain how awesome the freedom is to not have to wear a chest strap during workouts. I am training for an Ironman, which will probably take me 10-12 hours and am thinking of buying a second MIO link to switch out during transition so that I can have heart rate data for the entire event. At $99, I would still consider it a bargain if you needed to have longer term data and bought two units. You could then be charging one while the other is in use. Just a thought, but the price point certainly allows for this.

I'm thinking it's a bad unit. Ours works fine. Have used it for 4 1/2 months and haven't changed the battery once.

A couple of hours at most. My only criticism is that there's no on-screen warning that battery power is low. When it's out of power it just shuts off. Had mine over a year now; altho figuring out/finding some of the settings/controls is sort of quirky. considering the screen size and price I'm satisfied. It's held up better than I expected. And I like that I can play DVD's different regions.

There is not a low battery indicator, but the LED on the inside will start to get dimmer. You might also notice the need to turn the volume up higher as the battery wears down. With a standard alkaline 9v battery most people report 40-50 hrs of play time. Or if you use a rechargeable nimh 9v battery roughly half that per charge.

There is a small screen in the right hand corner. It has a picture indicator that tells you how much battery life it has left.

There is no low battery indicator. Just keep extra batteries and put them in when the sound is distorted or stops.

The batteries are in the unit and I haven't had any problems to check. I do like the unit....so do the neighbors.

Battery Life is pretty good on my unit. Played 3 hours continuously at the beach without charging.Sound is good and decently loud indoors but outdoors not so much. It is definitely not a "Bose" unit but under an umbrella at the beach it served our needs. Hope this helps.

There is no battery indicator nor does it tell you the battery level.......

I bought this for an older friend (89) who has macular degeneration and can only read with a CD player. When I visit her next, I will check and then respond. I know there is a window with the track # you are on, but I'm not sure about the battery life symbol. Will let you know. Oh, I just read the other 2 answers to your question, and yes, it appears the battery strength is also there.

I've run it for over 90 minutes total over several days on the high setting commuting to work with no indication it's running out of power. There isn't a low battery indicator on the light.

No low battery indicator. If you cover the unit in your hand you can muffle the sound and remove the pin to test it once a week. I got this for my daughter and its cool to hook on a purse, jacket zipper or a belt loop. No fumbling to push a button, just pull and it goes pretty loud.

There is no indicator light that tells you when it is charged. I use mine everyday at work. I try to plug it in overnight everyday. I have had three of these units in the last 11 years at work. They will last @ 5 years if using it everyday like I do.

I installed my unit the first of the year and I'm showing about 45% remaining. I don't use the unit all that much but I suspect the connectivity to the base unit (Elan in my case) is the biggest user of battery life. I might try Lithium next go around. I really like the lock/display...

Unit is strictly battery powered. It uses size AA batteries. For as much as I use mine, I judge the battery life to be pretty darned good.

Battery life is fair on the low setting. We ran ours only at night on a recent camping trip and it lasted three full nights and part of a fourth before quitting.

Due to many variables there is not an estimated time of battery life available. The unit does have a low battery indicator. The battery should be changed immediately once you see the LED light flash red and hear constant beeps for about 10 seconds after pressing the programming/enter "LockState" button. Please note: All settings are retained in the memory and will not be affected even if the battery is completely dead.
